Learning/Knowledge checks/Digital Design Fundamentals/Sequential logic and control/Check

Module checkpoint

Sequential logic and control knowledge check

Answer every question from your current understanding. After submission, compare your reasoning with the explanation and revisit any weak concept.

This check covers Storage elements, registers and counters, Finite state machines and safe control. Read them first if you have not.

6 QuestionsOne Answer eachImmediate ScoreDetailed Explanations

Read→Reason→Select→Review

Question 1 of 6When does a positive-edge D flip-flop sample D?

Throughout the clock-high phaseAt the rising clock edgeOnly while reset is active

Question 2 of 6Why is a clock enable normally preferred to a logic-gated clock in RTL?

It eliminates all dynamic power in the blockGating logic can glitch and skew the clockA clock enable updates registers asynchronously

Question 3 of 6What mainly distinguishes a Moore output from a Mealy output?

A Mealy output changes only on clock edgesA Moore output is a function of the state onlyA Moore output depends on inputs and state

Question 4 of 6What should an FSM define for an illegal encoded state?

Nothing, as it can never be reachedA hold in that state until power-offA deterministic recovery action

Question 5 of 6What is the key risk of using an asynchronous external signal directly in an FSM?

A combinational loop through the state registerMetastability and corrupted state transitionsExtra latency of exactly two clock cycles

Question 6 of 6What does a nonblocking register update model?

A continuous wire assignment with no stateRegisters all sampling old values at one edgeSequential updates, each seeing the previous one
